Derek is an amazing doctor and person. He treats every patient like a member of his family. He takes the time to educate parents and ensure our boys get the best. To my wife Serena and I Dr. D has always been there when we needed care for our boys. He’s simply the best!

Great doctor! Takes time to answer all of our questions. Amazing interaction with the kids. Takes the time to explains things to me (and my son). Yes, the wait can sometimes be long, but it's wait the time.

I met him with my child at Agoo in Laval a little while back. I immediately thought he was one of the best Doctors I had ever met. He listens to you and speaks with you and you never feel rushed. I walked out of there feeling much better about my child's situation. I would take him as my personnal physician without hesitation.

I started with him a few years ago when's child was very ill. He seems to be a very good doctor but waiting on average 1.5-3hrs to see him is unacceptable in my opinion. I have even had on more then one occasion the first appointment of the day and he strolls in a hour late. He has no respect for his patients time and the length of time they wait. If I could I would bring my children to another doctor. I also have found in the last few months he has developed a superiority complex and does not listen to patients as much as he used to
